What's in a bargain?

I've always been amazed by the concept of bargaining. I used to find it hard to believe that some people are able to bargain down prices to half and sometimes even quarter the original price. It even has its very own language with phrases recognized by everyone, at least over here. Like "Is that the final price?" or "How low are you willing to go?"

Some businesses are so tired of having their profits bargained away that a lot of them have signs that read "Bargainers NOT allowed here!" or something of the sort. And yet, when if you leave without bargaining, they call back to you and ask how much you want it for. Is there something wrong there?

I've always thought that there should be certain places in which bargaining shouldn't happen. For example, I hate it when I see people bargaining at an Adidas or a Nike Store, or at a Jeweler. It's just not very nice to look at. Places that you're good to go are the souks, markets, and the less fancy-looking places in general. You should bargain down the price of cabbage, not diamond.

However, there are expensive places, or the "high" areas as they call them here, that should always be bargained at. Like Khan Al Khalili, where I see tourist being scammed into paying 6 or 7 times more than what something is really worth. So if you're ever there, you can bargain down a price all the way to quarter easily.

(The above picture was taken in Khan Al Khalili, the best and worst place to bargain. Where a plane T-shirt can cost up to 60 or even 70 US Dollars, when in fact it cost like 15 Egyptian Pounds to make - about 3 dollars.)

The fact remains that bargaining an Egyptian pastime. Something that such a divided nation can actually agree upon. It's engraved in culture all the way back to the ancient Egyptians in their togas and stone money.

I love the concept of bargaining, but would never do it myself.
